Damped, Forced Oscillations & Superposition

Two SHM’s with same amplitude and time period, when acting together in perpendicular directions with a phase difference of π/2\pi/2, give rise to

Show answer and solution

Answer: (c)

  1. x=asin⁡ωtx = a\sin\omega t, y=asin⁡(ωt+π2)=acos⁡ωty = a\sin(\omega t + \frac{\pi}{2}) = a\cos\omega t.
  2. x2+y2=a2x^2 + y^2 = a^2: a circle, answer (c).
